To just have pictures for viewing you could use the Ascendo Photo Desktop. http://www.ascendo-inc.com/Photos.html
It's a good app for resizing and cropping photos to fit the size of you BB. It has a nice slideshow tool w/ a few nifty options. The software can not, however, get the photos onto your desktop. For that you would need to email them to the phone... which requires an internet service plan.
You could also post them to a web site and browse to it.
